An energy-efficient air conditioner starts with the right choice and proper installation, followed by smart usage. Below are tips for cooling and heating efficiently with your air conditioning.
- Choose an air conditioner with the right capacity for the room
- Use the air conditioner only when needed and configure it smartly
- Keep the filters clean and have the air conditioner serviced periodically
What makes an air conditioner energy-efficient?
The most important factor is the correct capacity: an undersized air conditioner constantly runs at full power, while an oversized one continuously switches on and off. Read calculating air conditioner capacity. In addition, a good location for the indoor and outdoor units and a leak-tight, properly charged refrigerant circuit are essential.
Optimal settings
Do not set the temperature extremely low or high, and turn the air conditioning off or down when leaving the room. If you also use the air conditioner for heating, this is often very cost-effective in spring and autumn; read air conditioning as heating.

Regular maintenance
Clean filters and periodic maintenance keep your air conditioner running efficiently. Read air conditioning maintenance.
